Yes since 2023, it's now taxed in Portugal if you hold for less than 1 year (until 2022 was tax free, even less than 1 year).

Exactly, it's similar as Germany. However Portugal has one more huge advantage : NHR (non habitual resident) tax-scheme.  You get this statut for 10years you are tax free on your foreign income (dividends, interests, royalties). Kind of temporary "territorial tax scheme".

Until 2022 private foreign pensions (for retired people) was tax free too under this scheme. Now it's taxed 10% due to other EU countries pressure.
